In Great Britain April 28, 1938 v x 23 Claims. (Cl. 1241s) The present invention is concerned with improvements in machines for operating on shoe soles, and is particularly, but by no means exclusively, concerned with machines intended for use by shoe-repairers for performing either a channeling or a rounding operation, or both of these, on repair-soles after they have been positioned on the bottoms of shoes.

Having regard to the fact that many shoerepairers are unable to afford expensiveshoerepairing machinery, and would, indeed, find difiiculty in correctly using apparatus of a complicated nature, it is desirable that machinery intended particularly for use by repairers should be of a relatively inexpensive character and should be simple and easy to operate. An eX- ample of a machine intended particularly for use in the shoe-repair-trade for rounding and channeling soles is shown in Letters Patent of the United States No. 1,463,823, Johnson et al., August 7, 1923.

One of the various objects of the present in vention is to provide an improved machine which will be suitable for channeling a repair-sole which is to be stitched to either a welted shoe or a McKay shoe and for rounding the sole in conformity, respectively, with the contour presented by the outer edge of the welt or by the side of the upper, or for rounding, without channeling a repair-sole which has already been permanently attached to a shoe-bottom, as by cement.

In the attainment of .this object, there is provided in an illustrative embodiment of the in- Ventio-n, hereinafter described, in novel combination, a work-supporting table, held against horizontal movement, a work-guide which pro vides both a face or flange for engaging either the edgeof the welt of a welted shoe or the side of the upper of a McKay shoe and a horizontal face or flange for projecting above the plane of the table and above the upper margin of a sole supported thereon and either beneath the welt of a welted shoe or beneath the feather of a McKay shoe. To allow the guide to be adjusted to different positions relatively to the rounding and channeling knives, as may be called for by the type of work to be performed, said guide is readily variable in position. The table has an opening across which a channelknife moves to out and feed the work. A foot engaging the upper face of the sole is movable above the table for cooperating with the channeknife to assist in the feeding operation. This foot, in one position, makes a cutting bed for the rounding knife.

Another foot, movably carried on the work-supporting table and positioned beneath the sole, rises to. clamp the sole against the upper foot and-provides means for holding the sole stationary while the channel-knife cuts the channel in the sole. The machine is readily which are to be attached to shoes by such-means asirivets' instead of by stitching, and for'this purpose may be 'providedwith easily manipulated means whereby the channel-knife may be lowered within the table-opening sufficiently to prevent it from operating on a so-lere sting thereon. With aview to providing a machine for rounding, without channeling, repair-soles which have alreadybeen'secured to shoe-bot adaptable forrounding, without channelingsoles toms by-"such means'as cement, in which work there-will normally be but a very narrow margin of sole-material projecting beyond the side of the shoe, the present invention further contemplates the. combination with a reciprocatory rounding knife, of a movable feed-foot engaging the underside of a sole to be rounded; and a device serving both as a cutting bed for the rounding knife and as a guide and feeding means for the shoe. .This device consists of a rotatable upper and the sole-margin in such a manner that the peripheral face of the roll engages the upper near to the sole. the workv in its advance, while the horizontal lower surface-of the roll engages the upper face of the sole-margin to provide the cutting bed. Beneath this horizontal surface the work-feeding member may move.

Other objects and'features of the invention will be developed in the following description.

In the. accompanying drawings:

7 Fig. 1 is: a side elevation of an illustrative further alternative form of work-engaging parts;

It thus serves to guide conical roll arranged to enter between the shoe- Fig. 10-,aside elevation, taken from the left I of the machine, of the parts seen in Fig. 9. I

Themachine has a vertical column I carry+ ing a head-casting, 3. Av forwardly and rearwardly extending shaft 5 is supported in hearings in the lower portion of the head-casting and has secured to the rear extremity a pulley by which it may be continuously rotated from a countershaft below it when an unillustrated, clutch-controlling treadle is depressed. At its forward portion, above the shaft 5, the head-casting has a vertical guideway for a bar 9 carrying a rectangular work-supporting table II at its upper end. The table is held by the thus-guided bar against horizontal movement, it having a smooth, horizontal upper face. The bar 9 has a stud l3 projecting forwardly from its lower end, and a sleeve |5 surrounding this stud has a depending rod H, which passes down through a lug I9 (Figs. 1 and 2) projecting from the lower part of the head-casting. A compression-spring 2|, located about the rod between the sleeve and lug, normally maintains the table II raised, a

collar 23 fixed to the rod below the lug serving to limit the upward movement of said rod. The lower end of the rod is connected by a link 25 to a treadle, by which the table may be lowered to facilitate the correct presentation of the work to the machine.

A normally stationary work-guide 21, against the under face of which a sole may be urged by the table and which therefore also serves as a heightwise gage for the work, is positioned above the inner portion of the table and projects horizontally a variable distance towards the middle thereof. This work-guide has a bar or shank 29, the rear portion of which fits within a guideway 3| formed in'an upstanding lug n the headcasting. The bar is releasably clamped in the guideway by a screw 33, so it may be adjusted along said guideway. At its forward, work-engaging end, the bar 29 is provided with a flange 35 extending towards the left, asviewed from the front of the machine, this presenting an outer vertical face. A second flange 31 projects horizontally from the lower edge of the flange 35 at its right-hand side and also extends slightly towards the right beyond the right-hand edge of the bar (Fig. 7). These flanges give the forward end of the bar an L-shaped appearance as seen from the side (Fig. 1). The flange 35 extends over an upper sole-engaging foot 39 and is recessed to receive said foot. Its vertical face provides a surface for guiding th'e'work into proximity to the rounding and channeling knives, as will hereinafter be explained. As will also later be'developed, the outwardly projecting flange 3'! on the guide is arranged either to support the welt of a welted shoe or to extend beneath the feather of a McKay shoe. In the former case, the Vertical face of the flange 35 positions the shoe transversely of the table II by engagement with the edge-face of the welt and in the latter it similarly locates the shoe by engagement with the side of the shoe-upper itself.

The table II has a rectangular opening 4| (Fig. '7) at its inner edge, and a channel-knife 43 projects upwardly through the opening, near its inner side, sufficiently to'cut a channel of the required depth in a sole lying on the table. The channel-knife is'held in a block 45 secured by a clamp-screw 4'! to the upper end of a carrierlever 49 which lies close against the inner face of the table-carrying bar 9 and is pivoted, about its lower end to engage the periphery of a cam 51 secured on the shaft 5. The rotation of the cam causes the channel-knife 43 to oscillate widthwise of the machine, said knife assisting in feeding the work as it moves towards the left and forming a channel in the sole in its movement towards the right. The lever 49, with the channel-knife, may be adjusted forwardly and rearwardly of the machine, so as to vary the position of the channel with relation to the edge of the sole. This is effected by a screw 59 which passes through a vertical slot 6| in the headcasting 3 and is threaded through the bar 9, it having at the front of the machine a hand-Wheel 63. Rotation of the screw causes it to move bodily in the bar. Thereupon, a flange 65 fixed to its inner end and lying in a groove 81 formed in the hub of the lever 49 causes said lever to move bodily along its pivot-stud This shifts the channel-knife forwardly or rearwardly transversely of the table II, its roll 55 then sliding across the periphery of the cam 51'. If it is desired to allow the channel-knife to oscillate idly without cutting a channel in a sole, as when opthis purpose, the block 53 which carries the pivotstud 5| is in the form of a slide mountedfor ad- J'ustment along a vertical slot 69in the carrierbar 9. A stem passing forwardly from the block through the slot 69, and also'through a slot in the guideway for the bar 9, has a wing-nut l3 threaded on its forward end and engaging the adjacent face of the bar. Normally, this nut clamps the block against shoulders upon the bar formed along the opposite sides of the slot 39 to hold the upper end of said block against the upper end of the slot. In this position, the channel-knife projects slightly above the table II to cut a channel in a sole supported thereon. By turning the wing-nut to unclamp theblock, the carrier-lever 49 may be lowered until the block rests upon the bottom of the slot, the channelknife then being shielded by the table against acting on a supported sole. Obviously, if desired, the block 53 may be clamped in any intermediate normal position between its limits. thus raising or lowering the axis of oscillation of the carrier-lever to cause it to form a channel of different depths in a sole. In order to determine the depth of the channel more accurately, the knife may be adjusted vertically in its supporting block 45 and held in. position by its clamp screw 41.

For rounding soles, the machine has a vertically reciprocating knife 15, the upper cutting edge of which extends horizontally transversely of the machine, and has a short angular extension 11 (Figs. '7, 8 and 9) at one extremity to assist in hOlding the sole stationary during the action of the channel-knife. The rounding knife is adjustably secured to the upper end of a vertically reciprocating rod 19, and is positioned opposite the center and just below the inner edge of the work-supporting table and near the center of the vertical flange on the work-guide 21. The rod passes down through a bearing sleeve 8| in the head-casting 3 (Fig. 4), and its lower end is pivoted to the strap 83 of an eccentric 85 secured on the shaft 5 near its forward end.

To provide a cutting bed for the rounding knife and also to assist the channel-knife, as itmoves towards the left (Fig. 2) to feed the work through the machine, the foot 39, in addition to engaging the upper face of the sole-margin, is moved to and fro transversely of the machine in time-relation to the oscillation of the channel-knife and the reciprocation of the rounding knife. The vertical flange 35 on the work-guide 21, beneath which the foot projects, is of such extent that said foot lies beneath it at both the left and right hand limits of its transverse movement. The foot 39 extends outwardly somewhat beyond the inner edge of the table H, above the opening in the latter and beneath the flange 35. It is secured to the under side of a bar 8? which is attached to an outwardly extending lever 89 pivoted about midway of its length on a pin 9! (Fig. 1) at the upper end of a transversely rocking carrier 93. The carrier is pivoted between its ends on a pin 95 on the head-casting. The lower end of the carrier embraces an eccentric 9'I (Fig. 6) fast on the shaft 5 and is rocked by 'it to move the foot 39 to and fro along the line of work-feed. The carrier has a lug 99 providing a vertical bearing for a reciprocating rod ml, which is joined at its upper end by a pin-and-slot connection I03 to the rear end of the lever 89. At its lower'extremity, the rod IOI carries a roll I05 (Figs. 1 and 5) engaging the periphery of a cam IIJ'I on the shaft 5. A tension-spring I88, connected between the carrier-lug and the head of the rod, maintains contact of the roll with the cam. By this arrangement, the foot 39 is moved down, when at the right-hand limit of its movement, to bear against the sole and is raised therefrom after the foot has moved across to the left, preparatory to moving back idly towards the right.

Means, additional to the rounding knife I5, is provided in the illustrative machine for assisting in holding the work against movement towards the right when the channel-knife 43 swings in that direction to cut a channel in the work. It consists of a serrated foot I559, for engaging the under face of the sole and lying within the opening in the work-supporting table II. The foot is so positioned in the opening, that it is beneath the upper foot 33 when the latter is at the righthand extremity of its stroke, at which time the channel-knife commences to move towards the right to produce its cut. The foot I09 is ar-' ranged at the outer side of the channel-knife and is formed upon a short arm'lII (Fig. 2), which is pivoted at its right-hand end beneath the table by a pin H3. .The lower edge of the arm IH has a projection I15 resting on a head Hfl at the upper end of a vertically movable rod H9. The rod passes down through bearings in the head-casting 3 and engages at its lower end a lever I2I, extending across the machine" and pivoted at I23 on the head-casting. The free end of the lever I2I carries a roll I25 contacting'with the periphery of a cam I21 fixed to the shaft 5 adjacent to the cam. El. By this means, the lower sole-engaging foot 99 is oscillated vertically about its pivot H3 in time-relation to the movements of the upper sole-engaging foot 39 and the channel-knife l3, it being raised to clamp the sole against the upper foot when the latter is in its lowered position at the right-hand end of its movement and just before the channel.- knife swings towards the right to cut the channel. The rounding knife IE will also be lifted when the upper foot is in the position last indicated, to cut through the sole to the level of the under face of the upper foot. Therefore, the work will normally be held against movement to wards the right during channeling, both by reason'of the sole being clamped between the feet and'because the rounding knife is then in the sole-margin. There may, however, be portions about the sole-margin where there is no surplus material for the rounding knife to cut through. Then the clamping feet alone may hold the work sufiiciently to resist the cutting action of the channel-knife. To hold the rolls 55 and I25 in constant engagement with their cams 51 and I21, respectively, the levers 49 and I2l have downwardly extending pins I29 secured to their lower ends, and a tension-spring 'I3I joining the pins pulls the rolls towards each other against their cams.

Since, in operating on welted shoes, the welt does not have to be cut in any way, the operator will cause the horizontal flange 31 on the workguide 2'! to pass between the underside of the welt and the sole-margin. To prevent the welt from buckling upwardly as it is pressed against the vertical flange 35 on the work-guide, there is provided a holddown I33 presenting a horizontally extending face I34, separated by about the thickness of a welt above the level 'of the flange Bl and against which the upper surface of the welt may abut. The holddown I33 is adjustably secured on the bar 29 and extends outwardly from. said bar, with a downward extension I35 lying against the flange 35 and on the lower edge of which is the face IM. 1 Assuming that a welted shoe is to be operated on, the operator will adjust the work-guide '21, if necessary, over the table I I until the outer face of its flange 35, which is to engage the edge of the welt, is in substantial vertical alinement with the cutting edge of the rounding knife 15. He may also adjust the channel-knife 33 to vary the distance from the sole-edge of the channel to be formed therein. With the machine thus adjusted, the operator depresses the treadle connected to the table, drawing it and the channelknife down against the-action of the spring 2|. He then rests on the table a sole secured to a welt/ed upper, and moves the work in to cause the flange 37 to be between the underside of the welt and the sole-margin. The upper face of the welt lies against the face I34 on the holddown I33 and the edge of the welt abuts against the flange 35. With the work thus positioned, the treadle is released, allowing the table to rise to press the sole-margin against the flange 3'! and thechannel-knife 43 also to rise.- The clutch for driving the machine is thereupon engaged and the power-cycle begins. By maintaining the edge of the welt in contact with the guide-flange 35, the operator correctly controls the transverse relation of the sole-margin to the roundknife and the channel-knife, and during each rotation of the shaft 5, the various instrumentalities operate as follows. The upper sole-pressv ing foot 39 is in a lowered position at the right hand or rearward end of its stroke, considering lowered and inactive and the lower foot I09 is also out of engagement with the sole. Before the channel-knife commences to swing back towards the right, the upper foot 39 is raised and moved across to the right-hand end of its stroke and is then lowered again to press on the sole.

The rounding knife 15 rises to cut the sole-margin against the upper foot as a bed, and the lower foot also rises, clamping the sole against the upper foot. The two feet and the rounding knife remain in the respective work-gripping and -penetrating positions just indicated, while the channelknife swings back to the right to form its out in the work. When it has reached the limit of its movement in this direction, the rounding knife and lower foot descend from contact with the work and the cycle is repeated.

For operating on McKay shoes, it is, in most cases at least, only necessary for the operator to remove the holddown I33 and to adjust the workguide 27 to such a position, that when the side of the shoe-upper is in engagement with its vertical flange 35, the desired width of the solemargin which is to remain on the shoe will extend between the flange and the rounding knife. Next, the shoe will be placed on the table II and moved in to cause the horizontal flange 31 on the work-guide to lie under the feather of the shoe between the upper and the sole. The machine will then operate as above indicated.

In case it is desired to round, without channeling, soles which are to be permanently attached to their shoes by riveting or nailing, the operator has only to slacken the wing-nut 13, which normally holds the channel-knife 43 in operating position, and lower the lever 49 sufficiently to allow the knife to oscillate idly within the table-opening 4! below the work.

With shoes which have had repair-soles permanently attached to their bottoms by cement and which it is desired only to round, it is not practicable to use a work-guide 21 of the kind above described, because the sole will have been secured fully to the edge of the shoe-bottom. Nor, by reason of the fact that it is generally desired in such work to leave only a very narrow sole-margin visible on the finished shoe, is it practicable to use, as a cutting bed for the rounding knife, the upper sole-pressing foot 39, intended to project an appreciable distance over the sole-margin. Therefore, for operating on cemented soles, the present invention contemplates the provision, in conjunction with a sole rounding knife, of a shoe-guiding member especially suitable for engaging both the upper and sole in the crease between the upper and narrow sole-margin, and which itself provides a bed against which the knife may act in rounding the sole close to the side of the shoe-upper. This guiding member takes the form of a freely rotatable roll I37 (Figs. 9 and 10) supported upon the head-casting on a vertical pin I39 depending from a bar 14-3 and positioned centrally of the width of the rounding knife 15. Conveniently, the roll i3? is substantially frusto-conical, with its larger end down. It may slope inwardly towards its upper end at an angle of about fifty degrees to the vertical, therefore having a suffieiently sharp lower edge to allow it readily to enter between the upper of a' shoe and the margin of a sole already fully cement-attached. The

periphery of the roll serves, by contact with the upper, to determine the transverse relation of the sele'to the rounding knife, while the lower extremity, lying above the plane of the table II, bot-h holds the sole-margin against the upthrust of the rounding knife and provides a bed for the latter to out against. However, in order to prevent the lower edge of the roll from forcing its way into the crease to an undesirable degree, and in order to improve the efficiency of the roll in controlling the relation of the work to the rounding knife, the sloping periphery may be reduced at the lower edge to provide a substantially vertical narrow wall. This wall, though generally vertical, may have about it a groove I 4| almost equal in width to the height of the wall. The relatively sharp edges formed at the top and bottom of the wall by the groove will increase the effectiveness of the positioning engagement of the roll with the work.

Since, in operating on repair soles which have already been cement attached to their shoes, it is unnecessary to employ a channel-knife, a machine for operating on such soles need only have, as its operating instrumentalities, such a rotatable combined work-guide and cutting bed device as above described, and a reciprocating rounding knife cutting against the underside of said device, though it may also have an oscillating feed-foot to assist in feeding the work. The machine first above described as being particularly suitable for use in rounding and channeling repair-soles for welted or McKay shoes may conveniently be modified in the following manner for rounding repair-soles of cement-soled shoes. The block 45 carrying the channel-knife is removed from its lever 39 and is replaced by a plain block I49 (Figs. 8 and 9), the upper face of which is level with that of the table II and which will, with the rotation of the roll l 31, assist in feeding the work. The upper sole-engaging foot 39 and the bar 29 providing the rightangled work-guide 2'! are removed from the machine. In place of the bar, there is se cured in the guideway 31 by the clamp-screw 33 a bar I43 extending outwardly and towards the left, it carrying at its outer end the roll I31, with the outer portion projecting over the rounding knife 15. After the foot 39 has been removed from its supporting bar 81, that bar may be swung up away from the rounding knife (Fig. 10), it being held there by a bolt I45 passing through a slot 14! formed in the bar and thread ed into the lever 89. With the bar 81 in this inactive position, it will provide room beneath it for the roll to lie over the'rounding knife.

In using the machine, simplified as above indicated, for rounding repair-soles of cementsoled shoes, the operator first pulls the worksupporting table H and the feed-block I49 down by means of the treadle, places the work thereon, and, after having allowed the table and block to rise, moves the shoe in until the upper at the crease engages the outer portion of the periphery of the roll I31 to locate the margin of the sole with respect to the rounding knife. The horizontal under face of the roll engages the upper face of the sole-margin, thus resisting the thrust of the knife upon the sole and furnishing a cutting bed for said knife. When the treadle is completely released to allow the table to rise fully under the action of its spring, said table and feed-block M9 press the sole firmly against the roll. After the knife has completed each work-piercing movement, its cutting edge striking against the under face of the roll at the end of its upward movement, and has been withdrawn, the feed-block moves across towards the left to carry the work through the machine, the roll I31 rotating freely to facilitate the feeding movement. At the conclusion of this movement of the feed-block, the rounding knife once more enters the work and remains within it, thus holding the work stationary, while the feedblock makes its return movement to the right.

(Fig. 8).

is a particularly useful instrumentality in the rounding of repair-soles for cement-soled shoes,

having at least three functions-positioning the i sole-margin in the correct heightwise relation to the rounding knife, providing a cutting bed for the knife to act against, and maintaining the work in the correct transverse position for a margin of the desired narrow width to be left on the rounded sole. The feed-block I49 engaging the underside of the sole is quite effective in feeding the work, particularly since the work-guide is freely rotatable, and there will be but little tendency for the work to move back towards the right with the feed-block in the idle movement of the latter, because of the absence of a channelknife when operating on cement-soled shoes. In addition, the action of the lower foot I 09 will provide more or less positive assurance against such backward movement, because it clamps the sole against the under face of the roll I 31.

As-an alternative to modifying the present illustrative machine in the manner just above indicated for rounding cement-attached soles, it

may be adapted for rounding such work, after the channel-knife block has been replaced by the block I 49, by removing the upper sole-engaging foot 39 from its supporting bar 89 and substituting for it a similarly shaped but narrower foot I5I This foot I5I extends only so faroutwardly as to project but slightly beyond the rounding knife J5 and is suited both to serve as a cutting bed for that knife and as a feed member, which in some measure clamps the sole for advance between it and the block I49. It is then only necessary further to remove the L-shaped work-guide 21' from the machine and to replace it by a guide I53, which has the same general shape as that guide as seen from the front of the machine but which lacks the outwardly projecting flange 31. The vertical face at the outer side of the guide I53 serves, as does the flange 35 of the guide 21, to guide the work by contact with the side of the shoe-upper. The omission of the flange 31 allows this, it avoiding entrance of the work-guide into the crease of the shoe.

Since in the majority of cases soles are, considered transversely of a shoe, curved upwardly somewhat on both sides of the longitudinal median line of the sole, when a cement-soled shoe is positioned on the table I l with the projecting margin of its sole lying underneath the roll I31 or the foot I5I, the operator may, by forcing the shoe against the table, either break or tend to break the cement bond between the sole and upper. To counteract this, there may be provided means to cause the shoe to lie on the table II so that its normally somewhat upwardly curved margin will be more or less horizontal, while the remainder of the sole will be adequately supported. This means comprises a'wedge-shaped block I55 (Fig. 10), held on the outer portion of a the table II by dowel-pins I51 extending from the block into holes I59 in the table. The block presents a downwardly and inwardly sloping face I6I. When a cement-soled shoe is positioned by the block on the table, it is canted downwardly and inwardly, so that portion of the projecting margin being rounded will be approximately horizontal.
